    • To much power for an old bike!!!
I want to preface this by saying the engine is a beast. They mean every bit of 100cc. With a few personal modifications I can push 50mph. My bike is 15 years old, and I'm very quickly having to replace old parts just to keep it up! Make sure to properly space the spark plug, it doesn't come spaced. Here's the down sides: it is a "one size fits all" motor, meaning it is made to fit a large space. It has modifications that come with it that help it fit other sizes, but not always well. I had to make personal modifications to the bike just to help the spark plug fit better. On that note, the carburetor doesn't fit inside the frame, so I have to keep it tilted, causing the engine to bog down. So far I have fixed this with a smaller oil mixture, but doesn't always help. I'm waiting on a piece to fix this, as well as a new carburetor for more power. Fluid filter is very weak, it broke the 3rd day, I had to buy a new one (there like 6 bucks for 2 tho so it's no problem). All in all worth the price! ... show more

    • Foreign Junk
Haven't even began to really get going on install and not impressed at all with the awful instructions (even for a pretty good do-it-yourselfer, so a parts list would be nice)...Missing gas cap (no contact # to help out with that so purchased a new tank that I don't need, just the cap. We'll see if the thing runs and lasts.... ... show more

    • Fun times , a couple negatives though
Review Image by Jason
Easy to install. Fun to ride. Everything works good. The stock carb came broken and customer service said they'd replace it but it would come from China and take weeks to receive it so I just upgraded to a different carb.. wish they would've sent me a refund for the money I had to spend. These same engines sell for more money on websites like bikeberry so this is a good deal for the $$$. I regret nothing about purchase. I upgrade the carb and exhaust and it goes 35mph.. Plan to upgrade a couple other things, hopefully can get this motor up to 45-50... Good motor to get yourself into the hobby. I guess only thing negative is if you get any broken parts, they send them from China... so hopefully everything arrives in one piece... but totally glad I made the purchase... fun hobby to get into. These have a one piece jug so you can't upgrade to a higher compression head.. but that's not a deal breaker for me. I recently ordered a new jug that I'm gonna port out and hopefully pick up some mph... braaaap brrrapppp braaaaaapppp.... love it! ... show more

Well let's say instructions weren't that great , YouTube video made it easier, getting sprocket on was the hard part, ended up having to buy a new bike as engine was too big, next the handle bars, the throttle cable handle grip was broken so unable to try engine out. Waiting on seller to remedy issue. ... show more

    • Not enough install instructions
Should have had vibration dampers included. The throttle cable was too long until it was broke in. Couldn't get it idle high enough. Had to the muffler vibrate loose twice. I added studs bolts with jam nuts. So far so good. Used thread locker on the studs.
